Gimme shelter.....

This is a frequent sight in our garden early in the morning at this time of year - a seven-spot ladybird holed up inside (well, almost inside) the follicles of a columbine seed head. I don't think they go in for anything that's edible - they just seem to find it a good place to spend the night.  

It's always worth avoiding the temptation to tidy up too soon in a garden in autumn, and instead leaving seed heads on plants throughout winter - aside from the seeds that they provide for birds, many provide shelter for small, overwintering insects.

Some, like this and this and this, also turn into very attractive 'skeletons'.

Theft in the flower border

Columbines are awkward flowers for bees to visit. They can reach the pollen by hanging from the stamens that dangle from below the flower, but the nectar is only accessible to insects with very long tongues. The nectar is secreted from the tip of those tall, tubular nectar spurs above the downward-pointing flower.

But within a few hours of opening all the nectar spurs in the columbines in my garden have holes ripped in them ............... and here....

..... is the culprit. Bumblebees must be able to smell the nectar inside the nectar spurs and quickly learn to short-circuit the legitimate route for extracting it, by simply using their powerful jaws to chew a hole in the nectar spur. Then it's easy to use their short tongue to suck out the nectar.

It always seems to be nectar-thieving bumblebees that chew the holes but honeybees soon learn to use this breach in the flower's security system.

When the columbines have finished flowering the devious bumblebees turn their attention to thieving nectar from broad beans, by chewing holes in the back of the corolla tube and so avoiding the effort and wear-and-tear that's involved in forcing their way between the petals at the front of the flower.
